Hi guys,
I know about the problem that things become loosen inside the muffler. I fitted the Align muffler on my YS 50 ST and it runs a while very POWERFULL but suddenly the engine wont run. I thought maybe that would be the bearings. Looked inside the engine and decided to buy a new YS 50 ST. So I bought the new YS50 and fitted the Align muffler again. But there is something strange. My muffler sounds really bad. I dont know how I can explain this sound but it really makes a loud GRRRRRR Like metal would touch metal:D... So I thought maybe there is loosen something inside. But if i shake the muffler with my hands I hear nothing. Could it be that something get loosen inside but is very tight so that it just began to vibrate during the heli is flying? Because I hear nothing when I just shake it with my hands. Hope you can help me :)
